My Chicest Colleague Keeps Wearing This Perfect Cashmere Jumper to the Office—Now It’s Back in Stock
Reformation’s cashmere Jadey knit has become the quiet hero of celeb and editor winter wardrobes. Here’s why we're choosing it over every other high-street jumper right now.
As a shopping editor, I spend a frankly unreasonable portion of my winter hunting down good cashmere. Not cashmere-adjacent. Not “10% cashmere blended with mystery fibres.” Actual, luxurious-feeling cashmere that still falls in the realm of the attainable. And when something genuinely good lands on the high street? The fashion desk talks about it for months. Reformation has always been in that conversation—the Clara Cardigan has held cult status for years—but this season, there’s another piece taking the lead: the Cashmere Jadey jumper.
V-neck knits are suddenly having a moment again, which feels slightly absurd to say, considering they have never been “out.” But fashion people have really re-adopted it this winter. Layered over a white tee, tucked into a tailored trouser or jeans, that little V instantly makes an outfit feel styled, and it leans into a knit that reads chic and streamlined, rather than chunky or cumbersome.

The Jadey hits every mark you want in a winter knit. The fit is that sweet spot: slightly oversized but still sharp, the handle feels expensive and most importantly, it’s made from 95% recycled cashmere. And the colours are so chic. Navy, rich brown, and more seasonal shades like a deep burgundy. This is the kind of knit that slips into a wardrobe quietly, then becomes the piece you wear twice a week without thinking.
Shopping Editor Florrie is a big fan, calling it "the perfect knit" and if you needed more proof the fashion world agrees, Kaia Gerber and Taylor Swift have both worn the Jadey, which feels like the ultimate endorsement.
